I. Understanding the Factors that Influence the Number of LED High Bay Lights

Before we dive into the nitty-gritty of calculations, let’s explore the factors that play a role in determining how many LED high bay lights you’ll need.

Space Size and Height: The Foundation of Your Lighting Plan

The first step is to grab your measuring tape and get to work! Measure the length and width of the area you want to illuminate, and don’t forget to note the ceiling height.

The larger the space or the higher the ceiling, the more lights you’ll typically need. This principle is fundamental in the field of architectural lighting, where experts often refer to the “more space equals more light required” rule. For a comprehensive understanding of architectural lighting principles, see the guide by the Illuminating Engineering Society, “IES Lighting Design Guide”.

Required Illuminance: Setting the Right Mood

Different spaces have different lighting needs. A warehouse might require a functional 300-500 lux, while a retail store aiming for a vibrant atmosphere might need at least 800 lux. Think about the activities that will take place in the space and the desired ambiance. Need to focus on intricate tasks? You’ll want higher illuminance. Looking to create a relaxing environment? Opt for a lower level.

Fixture Lumen Output and Efficacy: The Power of Light

Lumens, a unit of measurement for the total amount of visible light emitted by a light source, is a critical concept in lighting design. To delve deeper into this topic, consult the international standards set by the Commission Internationale de l’Éclairage (CIE), as outlined in their publication “CIE Lighting Guidelines”.

Consider the efficacy of your fixtures, measured in lumens per watt (lm/W), which indicates how efficiently they convert electricity into light. For more insights on choosing the right LED lighting, explore our guide on Choosing the Right LED Lighting for Your Space.

Now that we’ve explored the factors that influence your lighting needs, let’s get down to the brass tacks of calculating how many LED high bay lights you’ll actually need. We’ll guide you through the Lumen Method, a widely used approach for determining fixture quantity, and also introduce some handy online tools and resources.

The Lumen Method: A Step-by-Step Guide

The Lumen Method is a systematic approach to lighting calculations that considers various factors to ensure adequate illuminance in your space. Let’s break down the steps involved:

1. Calculate the Room Cavity Ratio (RCR): This value helps determine how efficiently light reflects within the space. You’ll need the room’s dimensions (length, width, and height) to calculate RCR.
2. Determine the Coefficient of Utilization (CU): This factor accounts for the light loss due to absorption by surfaces and fixtures. You can find CU tables provided by lighting manufacturers or online resources based on your room’s RCR and the reflectance values of your walls, ceiling, and floor.
3. Apply the Lumen Method Formula: The magic formula is: Number of fixtures=(Area×Illuminance×LLF×CU)(Lumens per fixture×Number of lamps per fixture)Number of fixtures=(Lumens per fixture×Number of lamps per fixture)(Area×Illuminance×LLF×CU)​
   • Area: The total area of the space you want to illuminate.
   • Illuminance: The desired lighting level in lux (or footcandles).
   • LLF (Light Loss Factor): Accounts for the depreciation of light output over time due to dirt, dust, and lamp aging. Typically ranges from 0.7 to 0.9.
   • CU (Coefficient of Utilization): Obtained from CU tables based on RCR and reflectance values.
   • Lumens per fixture: The total light output of a single fixture.
   • Number of lamps per fixture: Some fixtures have multiple lamps, so include this if applicable.
4. Example Calculation: Let’s say you have a warehouse with an area of 10,000 square feet, a ceiling height of 20 feet, and you want to achieve an illuminance of 300 lux. You’ve chosen LED high bay fixtures with 20,000 lumens output and an LLF of 0.8.
   After calculating the RCR and referring to CU tables, you find a CU of 0.6. Plugging these values into the formula, you get:
   Number of fixtures=(10,000×300×0.8×0.6)(20,000×1)=72Number of fixtures=(20,000×1)(10,000×300×0.8×0.6)​=72 So, you’ll need approximately 72 LED high bay lights for this warehouse.
